The spark plugs in your HHR are located under the ignition coil assembly on the top of the engine.
Under the ignition coil, top of each cylinder. You have to remove the covers on top of the engine to see them.
How does that cover come off? Do you just pull it off or is it bolted on? I don't see any boltheads to loosen.I have the owner's manual for the 2010 HHR, but it does not tell how to remove cover over sparkplugs.
